Lame. Since I couldn't make it Saturday, I went poking around to all the old entrances I used to know of, even some most folks don't know about, and found every single one gated off. Looks as if the last available open entrance (without joining a ridiculously priced offroad club) is the subdivision. I will be doing some more poking around soon, as I believe there may be some older trails up to the top that might be able to be resurrected.
